There is going to be some major maintenance at Stanford on Monday May 18 in the morning (Pacific time). Most of FAH will be up, but right now, the stats web site looks like it will be down. Also, it is possible that the GPU AS and PS3 AS will be down, although we are working on migrating those this week to avoid downtime. The data servers (work servers) should all be up. Stats updates will be suspended briefly during this period as well, but will start back up (with no WUs lost) after we're done.
I'll post more as we have more to say. At its worst, those servers should only be down for about 3 hours, assuming all goes well with the infrastructure work being done.
